Hi everyone,

I am actually installing Openstack Havana on my Debian Wheezy server using the official Openstack tutorial. But as some others I encounter a problem at Nova's Compute install.

My apt sources.list are actually like:

>deb http://ftp.uk.debian.org/debian/ wheezy main
>deb-src http://ftp.uk.debian.org/debian/ wheezy main

>deb http://security.debian.org/ wheezy/updates main
>deb-src http://security.debian.org/ wheezy/updates main

>deb http://ftp.uk.debian.org/debian/ wheezy-updates main
>deb-src http://ftp.uk.debian.org/debian/ wheezy-updates main

>deb http://archive.gplhost.com/debian havana-backports main
>deb http://archive.gplhost.com/debian havana main

When using: "aptitude install nova-compute-kvm" I encounter the following dependency error (there seems to be some inter-dependencies that are making troubles here):
